Generic plot types in R software


Introduction

plot() function is the generic function for plotting in R. It can be used to create basic graphs.

A simplified format of the function is

plot(x, y, type="p")
  • x and y: the coordinates of points to plot
  • type : the type of graph to create; Possible values are :
  • type=“p”: for points (by default)
  • type=“l”: for lines
  • type=“b”: for both; points are connected by a line
  • type=“o”: for both ‘overplotted’;
  • type=“h”: for ‘histogram’ like vertical lines
  • type=“s”: for stair steps
  • type=“n”: for no plotting

Examples

x<-1:10; y=x*x
plot(x, y, type="b")
plot(x, y, type="h")
plot(x,y, type="s")
